Before PowerShell, I spent the first third of my career as an IT Pro pointing and clicking in the GUI and I decided to write this book to save IT Pros from themselves who are reluctant to learn PowerShell. Instead of a book that just covers topics with fictitious scenarios, this book is more of a condensed version targeting the specific topics that I’ve found an IT Pro needs to know initially to be successful with PowerShell in a real world production environment. It’s a collection of what I wish someone would have told me when I started learning PowerShell along with the tips, tricks, and best practices that I've learned while using PowerShell during the past 10 years. This book focuses on PowerShell version 5.1 in a Microsoft Active Directory domain environment running on Windows 10 and Windows Server 2016. All currently supported versions of Windows and previous versions of PowerShell beginning with PowerShell version 1.0 are briefly mentioned in this book.
